Beyoncé Dishes on Her Sassy Alter-Ego

The pop diva born Beyoncé Giselle Knowles has another moniker  and a spicy persona to go along with it.

Meet Sasha Fierce! The former Destiny's Child member, who releases her third solo album, I Am… Sasha Fierce on Nov. 18, said in a statement Tuesday, "I have someone else that takes over when it's time for me to work and when I'm on stage, this alter ego that I've created that kind of protects me and who I really am."

Her alter ego has far fewer inhibitions than Beyoncé Knowles herself, said the Grammy Award winner. "Sasha Fierce is the fun, more sensual, more aggressive, more outspoken side and more glamorous side that comes out when I'm working and when I'm on the stage."

Of the double album itself, which features the No. 1 iTunes hit "If I Were Boy," Beyoncé, 27, said it "allows me to take more risks and really step out of myself, or shall I say, step more into myself, and reveal a side of me that people [who] only know me see."

One of those who knows her best is rapper/mogul Jay-Z, 38, whom she wed in April. Although the couple have been tight-lipped about their relationship, Beyoncé recently spoke more candidly than ever about the union with just three words: "I'm married now," which she said while discussing recent changes in her life on the opening video montage at a listening party for her upcoming album at Manhattan’s Sony Club on Wednesday night.
